Subject: RE: [Leica] Degradation with filters

Erwin,

Have you ever done any analysis of an image (say one that isn't prone to 
filter issues) with and without a filter, and seen that there is an image 
quality degradation with a filter?

Aside from that 'best case' test, to you have any qualitative analysis on 
other situations?

Thanks.
